MINING APPARATUS.

Application medium is, 1924. Serial no. 720,420.

My invention relates to mining apparatus.

.liri'object of my'invention is to provide Another an improved mining apparatus; object of my inventionis to provide 2111- proved miningapparatus especially adepted to use in entry or rooincutting where itis desirable for the machine to operate'irom its truck. A. further object of my invention is to provide an improved mining apparatus of the mounted type having an independent propulsive mechanism in the form of a power drum mounted thereon adapted to wind in a cable secured at an extraneous point in advance or in thercar of the truck and having improved guiding means for the cableand an improved general arrangement of parts. These and other objects and advantages of my invention will, however hereinafter more fully appear.

In the accompanying drawings l have shown for purposes of illustrationone' form which my invention may assume inpructice.

In these drawings,] r

Fig. 1 is a plan view of a min ng appaatus constructed in accordance with myimprovement, the mining machine being removed therefrom and certain portions being broken away to facilitate illustration. Fig. 2 is a side elevation of the mining apparatus shown in Fig. 1 with the mining machine in operative position thereon.

Flg. 8 IS a detailed front end elevation partially in section, oi a portion of my 1111- 1 proved guid'ng arrangement. a i In this lllustrative construction I have shown a mining machine and truck of the same general character as that described and claimed in a pendingapplication, Ser. No. 701,390, filed Mar. 24-, 192 1 nated 5, in such a manner that the body portion lis imiintamed parallel with the trackelevated positions.

way in its different Mounted upon the adjustable body portion 1- is a complete mining machine, generally desgnated 6, of the bottom cutting type although it may beo'l any suitable ty' pe butis herein of the well known chain ted room" and pillar type, having a suitable driving motor, herein a pressure fluid actuated driving motor (not shown) and 'a projecting cutter bar 7 prov'ded with an endless cutter bit carrying cutter chain 8 adapted to be circulated about the cutter bar in a well known n'ianner. The machine 6 is mounted upon a swivel member 9, which is secured to the body portion d, about which the mining machinefs adapted to pivot to cut an arcuate kert' intheworlring face of the coal through any suitable power drivingconnec-- tions from the drivingunotor. Mounted upon the rear end of the adjustable body portion lot the truclr is provided a propul sive mechanism of improved torm adapted to move the miniru apparatus relative to the trakway. r

In 1 my improved construction it will be noted that I have mounted on the bodyportion 41 a propulsive or reeling mechanism generally designated 10 which is adapted to wind in a fiexiblemember, herein a cable 11. This reeling mechanism, which likewiseisa l-Iolmesinvention, comprises a unidirectiona pressurelluid actuated driving motor, a por-' tion of which is indicated at 10", disposed within the drum of the reeling mechan sm, the rotation of the drum being controlled by a reaction mechanism, generally desig nated 12 including a brake band 13 and brake band applying mechanism including a lever 1 L pivoted at 15 to a downwardly projecting rod 16, which is in turn pivoted at 17 ton crank 18 adapted to be operated by a lever 19 disposed adjacent the operat ing side 01' the truck. The drum is provided with a brake band 20, having a suitable operating handle 21, wh'ch is adapted to control or brake the rotation of the drum when the reaction control mechanism 12 is released, for instance, when the mining appa ratus is moving down a trackway of a steep gradient. Pressure fluid is adapted tobe admitted to the drum driving motor til) through a pipe connection 22 under the control of a throttle valve 23, which pipe connection communicates through a pipe con nection 24c leading in any suitable manner to a hose reel 25 suitably mounted on the rear end of the adjustable body portion a and which is adapted to wind in or pay out a hose 26 the mining apparatus moves along the trackway and through whichhose pressure fluid passes from any suitable source of supply. A guiding mechanism, generally designated 2?, guides the hose as it is wound in or paid oit from the reel.

In my improvement it will be noted that when it is desired to move the mining apparatus forwardly along the trackway the cable 11 is passed from the top or the drum of the reeling mechanism 10, beneath a guide roll or sheave 28, slidably mounted on a transversely extending. horizontal shaft 29 supported by suitable standards 30 carried upon thebody portion 4, and forwardly over a guide roll 31, journaled on a transversely extending horizontal shaft 32, forwardly beneath the mining machine and its cooperating parts over a transversely extending horizontal guide roll 33-, jourl'ialed as at 3% in bearing members 35 suitably secured as by bolts to transversely extending plate members 36 which arein turn suitably secured to longitudinally extending parallel angle irons 37 forming a portion of the body portion a of the truck. The cable 11 is then guided laterally over the roll 33 by means of guide sheaves 38 rotatably mounted upon vertical studs39 disposed in the same verticalpplane as the axis of the guide reel 33, the cable then passing forwardly along the trackway to a suitable stationary abutment, for instance, a rail clamp or the like. When the cable is in this position the throttle valve 23 is manipulated by the operator permittin pressure fluidto pass through the hose an, the reel connections, and pipe connections 21 and 22 to the drum driving motor. The op erator then manipulates the handle 19 which applies pressure to the brake band 13 operating the reaction control inechai'iisni 12. cansing the drum to be rotated in a clockwise direction as viewed in Fi 2, winding in the cable and consequently. moving the mining apparatus forwardly along the trackway.

As the cable is wound onto the drum. the guide sheave .28 moves back and forth along the shaft 29 causing the cable to be wound evenly onto the drum in the usual manner.

When it is desired to move the mining ap versely of the, truck around a guide sheave 40, journaled on a vertical stud ll. suitably secured to a detachable bracket member 42 which isprovided with an inwardly projecting cylindrical portion 43 adapted to be inserted in a bore 44: formed in a carrier member 45 suitably secured to the cross plate members 36 of the truck. The bracket incur ber 42 is provided with an inwardly projecting lug 45 adapted to engage the side at the carrier member 45 thereby preventing rotation of the bracket about the cylindrical portion 43. The bracket member is also provided with an upwardly extending arcuate guiding portion 46 which prevents the cable from dropping oil the sheave when the cable is slackened. The cable then passes from the sheave 4O rearwardly along the side of the mining apparatus around a guide sheave d7, similar to the sheave 40. rotatably mounted upon a stud 48 suitably carried by a bracket 49 which is adjustably carried by means of a set screw connection upon a b aclret 50 suitably secured to the truck body portion at, and the cable then passes transversely of the truck and around the guide sheave 51 rotatably mounted upon a vertical stud 52 carried b i a bracket :33 suitably. secured to the truck frame. It will herein be noted that the bracket 49 may be swung in out of the way when not in use, if desired, by simply releasing the set screw. The cable then passes rearwardly along the trackway to a suitable extraneous stationary abutment. The drum of the reeling mechanism 10 is then again actuated, thus reeling in the cable, and consequently moving the mining apparatus rearwardly along the trackway.

As a result of my improvement it will be noted that I have provided an improved mining apparatus propulsive mechanism having an independent driving motor which is of exceedingly simple anducoiupact form and which may be applied to a truck of standard construction with a minimum of change. It will further be noted that I have provided an improved unidirectional propulsivc mechanism adapted to move the mining apparatus in either direction along the trackway by means of a flexible cable and which includes improved guiding means for the cable.

l/Vhile I have in this application described one form which my invention may assume inpractice, it will be understood that this form of the same is shown for purposes oi illustration and that the invention may be modified and embodied. in various other forms without departing from its spirit or the scope of the appended claims.
